Pregnant women with verified pelvic girdle pain between weeks 20 and 32 of gestation logged nightly pain scores and sleep quality metrics before and after mattress intervention.
Tested whether specialized pressure-relieving sleep surfaces and contoured pillows designed to cushion the pelvis and shoulders relieved pregnancy-related pelvic girdle pain (PGP).
Accommodates widening pelvis in side-sleeping posture, keeping the sacroiliac joint in neutral mechanical resting position.
Pushes upward against the greater trochanter, exerting painful shear forces across the relaxed pelvic ring.
Women sleeping on contouring pressure-relief sleep systems experienced a 41% drop in nocturnal pain intensity and a 52% reduction in nightly pain-induced awakenings compared to standard care.
During pregnancy, relaxing pelvic ligaments make hard beds extremely painful for side sleepers. Gentle body-contouring pressure relief is vital to take shear strain off the sacroiliac joint.
Recommended Firmness Target: 5.0 to 6.0 out of 10 (Plush-Medium to Medium)
Pregnant women should choose mattresses with thick contouring comfort layers and pair them with a supportive knee pillow to align the hips.
